This invention relates to certain new and novel im rovements in by-product coke.

15 pig her objects and advantages ofthe inven- -tion will become apparent during a study of the following description taken in connection with the accompanying drawings clearly illustrating the invention as applied "thereto. I

Figure2 is a fragmentary detail sectional view taken throug the charging passages and the auxiliary passages which communicate with the former.

Figure 3 is a view similar to Figure 2, showing the modified form of buffer discharging passage.

With reference more in detail to the drawings, it will be seen that I have designated the oven generally by the reference character 0, the same being provided with the bottom or level end thereof with the usual coke chamber designated generally by the reference character C.

The top wall of the coke chamber is designated generally by the reference character W. As is well known in the art, the topwall of the coke chamber of a byroduct coke oven, is provided with a plura ity of openings better known in the art as charging holes through which coal is passed downwardly to the coke chamber of the oven. Abutting the present invention is the wall W of the coke oven and wherein the top thereof is rovided with usual plurality of longitudina y spaced charging holes 5.

Holes 5 with the chamber Care a plurality of charging passaes which extend vertically through thewall The charging passages altho really one vertical assa'ge to coke chamber are designated each as in pairs for convenienceof description of cross sectional view in relation to passages 9 that maybe designated as auxiliary collecting passages, each pair so designated includin an upper passage 6 and a lower passage 7 1n longitudinal alignment with the upper passage 6. .0 Passage 6, as is apparent at its upper end, opens into, or at its re 'stry with the hole 5 in the wall W, while t e lower passage 7 at ..'its lower end opens inwardly to the chamber Figure 1 is a vertical longitudinal sectional C view taken through a cokefoven for more a As is also known in the art, there extends through the wall W at one end thereof, and in vertical spacedvrelation to the charging passages, a standpipe which in the present instance, is designated, by the reference charo acter 8. The standpipe 8 which extends ver tically through the walls W, has its lower open end indlcating with the chamber C, and at its upper end the standpipe 8 projects beyond the top or upper face of the wall'W.

At each end there is provided an elongated longitudinally extending passage 9, formed in the wall W extending longitudinally of the wall parallel to the chamber C The passagesv9 which may be designated as auxihary collection passages extends between the upper and lower passages 6 and 7 of the pairs of passages, the upper passage 6 of said pairs of passages, opening into the passages 9 at the bottom of the passage 6 and the' lower 35 r passage 7, opening at its upper end into "the bottom of thepassages 9; j' a Y The passages 9 at that end farthest remote from the standpipe8 is of course closed while the passage at its open end the same passage 9 is opened into standpipe 8, laterally of the pipe, as in Figure '1.

From the foregoing then, that coal may be passed through the holes 5, and the pairs of passages 6 and 7 leading therefrom in the chamber C to seek the de-. sired level without stoppage by coal of passa s 9 so that passages 9. can function during co ing process as intended by this'invention.

During the'operation of the-oven, the passages 9 in conjunction with the charging passages 7 provides a by-pass from the chamber C to the standpipe 8 so that parts of the occluded gas will be conveyed therethrough to the standpipe to pass upwardly and outwardly at the open upper end of the standpipe.

, Parts of the-occluded gas will of course be left to be drawn over the leveled charge of the coal in the chamber C, toward that end of the chamber at which the standpipe is located to pass upwardly through the lower open end of the standpipe as is at present the casein all types of coke ovens.

' The purpose of'the arrangement of paspassage,

.' sages 9, to passages 6 and 7 (charging holes) is intended as an auxiliary means for carrying the gas to the standpipe and is not intended in any way to abandon entirely common practice of drawing gas over the level charge to the stan-dpipe, but only to complement that passage.

The mouths of the passages 6 and 7 where the passages connect with the passage 9-, are especially designed for protection against blocking the passage by piling coal in charging (although this pilingwill not occur if the leveling process is properly timed). In this connection and as shown to advantage in Figure 2, thevupper passage 6 of the pair of passages at its lower end is reduced to provide a restricted discharge neck 6 which at the opened lower end of the passage6 is cylindrical with the top of the passage 9.

In Figure 3, it will be seen that the passage '6 at the lower end thereof, is substantially the same in diameter at its discharge mouth 6a as at any other point in the length of the in other words, the passage 6 being of uniform diameter from its lower to its upper end but of less diameter than passage In regard to the mouth of the passage 7, at the upper end of the passage, the mouth is flared as at 7' as is evident from a study of Figures 2 and 3 irrespective of whether the passage 6 be of uniform diameter throughout its length as in Figure 3, or having a fixed mouth 6' as in Figure 2.

It is thought thatfrom theforegoing description, taken in connection with the accompanying drawings, aclear understanding of the operation, advantages and utilitv of an,

invention of this character will be hadby those skilled in the art, without a more detailed description.

it will be seen mum:

proximate maximum volume and distance 5 from level coal to roof of oven is least; namely a new charge. It can readily be seen by those skilled in the art, that gas, so by-passed through charging holes and designated auxiliary collecting passages will have shorter distance to travel in hot zone, and will thus never reach as high an initial temperature. Furthermore such an arrangement of a bypass will eliminate much of the gas travel from ovens to 'flues which at present is excessive on new charges, due to the built-up pressure, and which not only cools the flues and causes'a latent heat loss to stack, but represents a loss of gas to stack as well as a loss of gas through doors and jambs. Furthermore the very elimination of these losses means near compliance with various smoke nuisance laws.

Furthermore this arrangement of a bypass will in all probability result in less ammonia broken'up to cyanides, less condensedpolymerization of benzol to naphthalene by heat and further to permit of cooler gas delivered to the gooseneck. (The gooseneck as is well known is connected between the standpipe) otherwise known as an ascension pipe and collecting main.

Even though I have herein shown and described the preferred embodiment of my invention, it is to be understood that the same is susceptible to changes fullycomprehended by the spirit of the claims as herein described, and the scope of the appended claims.

Having thus described my'invention, what I claim as new is:: a

1.-In combination with a coking chamber and a stand pipe connected therewith, a bypass for gases leading from the coking chamber to the stand pipe and having lateral branches'providing coal charging passages for the coking chamber; the by-pass and branches being arranged in the roof of the' coking chambers 2. In combination with a coking chamber and a stand pipe communicating therewith, a passage for gases leading laterally from the stand pipe and having vertical branches providingcoal charging-passages for the coking chamber, said passage and vertical branches being arranged in the roof of said coking chamber.- v

3. In'combination, a coking chamber, a stand pipe communicating therewith, a horizontal passage for gases leading from said such stand pipe and having vertical branches leading to said chamber, said passage and branches being arranged in the roof of said chamber, and said branches havin upper ends opening outwardly of the cham r and lower endsopening intosaid chamber whereby to provide coal charging passages for said chamber.

In testimony whereof I afiix my signature. PAUL M. PIN CKABD.
